SPL: Port SPL framework to powerpc

2012-12-05T16:30:22Z

This patch enables the SPL framework to be used on powerpc platforms and not only ARM. timer_init() does not exist on PPC systems. The timer (decrementer) is initialized and enabled in interrupt_init() here. And currently interrupt_init() is called after relocation to SDRAM. Since the only powerpc SPL implementation (a3m071) doesn't need a timer, let's remove this timer_init() call for PPC systems. Signed-off-by: Stefan Roese

spl/powerpc: introduce CONFIG_SPL_INIT_MINIMAL

2012-11-26T21:41:24Z

cpu_init_nand.c is renamed to spl_minimal.c as it is not really NAND-specific. Signed-off-by: Scott Wood --- v2: factor out START, and change cpu_init_nand.c to spl_minimal.c Cc: Andy Fleming

powerpc: change .fixup test to a GCC version test

2012-11-26T21:41:22Z

This was introduced by commit 244615197469dd6fe75ae082f38424b97c79aeaf, but it fails in a minimal SPL build where the only thing in arch/powerpc/lib is cache.c, which apparently doesn't generate any fixup records. The problem is reported to occur with GCC 3.x, so insist on GCC 4.0 or newer. Patterned after checkthumb as suggested by Tom Rini. Signed-off-by: Scott Wood Cc: Peter Tyser Cc: Tom Rini -- v2: test gcc version instead of testing nothing

split mpc8xx hooks from cmd_ide.c

2012-10-17T14:59:08Z

move most of mpc8xx hooks from cmd_ide.c into ide_preinit() and newly created ide_init_postreset() (invoked after calling ide_reset after ide_preinit), some cleanup to make checkpatch happy, enable IDE init hooks in configs of affected boards. confusingly, these hooks are used by more than just mpc8xx-based boards, and therefore are placed in arch/ppc/lib/ note: checkpatch still emits warnings about using volatile Signed-off-by: Pavel Herrmann

Consolidate bootcount code into drivers/bootcount

2012-09-01T12:26:02Z

This patch moves all bootcount implementations into a common directory: drivers/bootcount. The generic bootcount driver is now usable not only by powerpc platforms, but others as well.

powerpc: Minimal private libgcc to build on Debian

2011-12-07T22:04:32Z

Standard Debian powerpc and powerpcspe systems only include hard-float libgcc in their native compilers, which causes scary build warnings when building U-Boot. Debian and other PowerPC-supporting distributions used to provide libgcc and other libraries in a "nof" (soft-float) form in the "multilib" packages. As they were completely unused by the distribution and therefore tended to be very buggy it was decided to save some time on the part of the maintainers and build-servers by removing them. Admittedly, right now the linker warnings do not indicate any problems, as the included routines do not use any floating point at all. The concern is that if floating-point code were ever added it might cause hard-float code to be unexpectedly included in U-Boot without generating a hard error. This would cause unexplained crashes or indeterminate results at runtime. The easiest way to resolve this is to borrow the routines that U-Boot needs from the Linux kernel, which has the same issue. Specifically, the routines are: _ashldi3(), _ashrdi3(), and _lshrdi3(). They were borrowed from arch/powerpc/kernel/misc_32.S as of v2.6.38-rc5, commit 85e2efbb1db9a18d218006706d6e4fbeb0216213, and are GPLv2+. The Makefile framework was copied from the U-Boot ARM port.

Switch from archive libraries to partial linking

2010-11-17T20:02:18Z

Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier

ppc: Conditionally compile bat_rw.c

2010-10-13T19:44:10Z

Only a few PPC boards actually use the common BAT manipulation functions, so only compile it for them. Signed-off-by: Peter Tyser

MPC512x: workaround data corruption for unaligned local bus accesses

2010-06-29T12:41:37Z

Commit 460c2ce3 "MPC5200: workaround data corruption for unaligned local bus accesses" fixed the problem for MPC5200 only, but MPC512x is affected as well, so apply the same fix here, too. Signed-off-by: Wolfgang Denk Cc: Detlev Zundel Cc: Anatolij Gustschin Acked-by: Detlev Zundel
